Why is there a rubbish chute in Singapore?

Why is there a rubbish chute in Singapore? The one common feature of all HDB flats and many private apartments today is this: the ubiquitous rubbish chute which makes it convenient for residents to get rid of their trash. But ask Singapore Environment Council executive director Howard Shaw about it and he will tell you the rubbish chute is one thing that Singapore’s builders ‘got wrong’. Why are there no recycle bins in Singapore? In a recent straw poll of 50 people conducted by The Sunday Times, the majority said that Singapore’s existing infrastructure does not encourage recycling. The problems:...

Which of the following is an example of biological pest control?

Which of the following is an example of biological pest control? An example of biological control is the release of parasitic wasps to control aphids. Aphids are a pest of plants and cause huge damage to plants as they remove nutrients from the plant. The parasitic wasp lays eggs in aphids, as shown in the movie. What do you mean by biological pest control? Biological control is the release of an organism that will consume or attack a pest species resulting in a population decrease to a level where it is no longer considered a pest. What is an example...

Will reducing pipe size increase pressure?

Will reducing pipe size increase pressure? The tighter you squeeze your thumb, the more the flow is reduced, and the greater the pressure you feel will be. But you haven't created any NEW pressure. The smaller pipe would restrict the flow of water. The reduced flow would reduce the pressure loss in the pipes, resulting in more pressure. Does a larger diameter pipe increase water pressure? Increasing the pipe diameter won't change the static pressure (the pressure when no water is flowing). When you open a spigot, however, the water pressure at that spigot decreases somewhat, and because a larger...

How long do nasturtiums take to grow?

How long do nasturtiums take to grow? about 10 to 12 days Start indoors in pots: Put two seeds (1" deep) in each pot and grow them under lights or in a bright location, such as a south-facing window. It takes about 10 to 12 days for nasturtiums to germinate. Do nasturtiums like sun or shade? Soil should be well-draining. Plant nasturtiums in full sun (6–8 hours of sunlight) for the best results. They will grow in partial shade (3–6 hours of sunlight), but won't bloom as well. Do nasturtiums grow back every year? They germinate quickly, grow quickly too,...

Why is air detrimental a hydronic heating system?

Why is air detrimental a hydronic heating system? Air in a hydronic system is bad news because 1) dissolved air in the water will corrode/rust any piping or equipment made of ferrous materials and 2) free air within the piping will prevent flow, either partially or fully. Air lock within a piping system can stop flow as effectively as a closed valve. What does air do to a hydronic system? any air in the piping system rises to the high points. This air must then be vented out of the system. If the air is allowed to gather at these...

Do heat pumps also dehumidify?

Do heat pumps also dehumidify? Dehumidification Made Easier As with an air conditioning system, a heat pump also offers the ability to remove excess moisture and reduce indoor humidity levels. Cooling mode – As the heat pump operates in cooling mode, it also removes moisture via condensation. Will a heat pump get rid of condensation? Heat pumps are primarily used for heating and cooling but also have dehumidifying benefits that combat excess moisture. While heating, heat pumps can dry out window condensation. But the devices also have a dehumidifying mode which can be set to offer even more effective moisture...

Is evaporation heating or cooling?

Is evaporation heating or cooling? Evaporation is the cooling process. Evaporation has a phase change from liquid to a gas. Heat energy is absorb by the liquid causing it to become a gas. Why is cooling caused during evaporation? Evaporation is a surface phenomenon where any liquid can release its molecules in the air by using the surrounding heat or the heat from the liquid itself. It is because the water molecules absorb the heat of our body and convert into gas molecules. The heat lost from our skin makes us feel cooler. Is heat released during evaporation? In the...

How does heat travel through the house?

How does heat travel through the house? Heat is transferred to and from objects -- such as you and your home -- via three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows. Where does heat come from in a house? The majority of North American households depend on a central furnace to provide heat. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type...
